Not sure offhand, but I'm sure the course notes you have (or books) will answer that

Bit rate is the amount of data that is used to sample an analog signal for a given period of time. This essentially determines the resolution and quality of the audio and how fine the range of frequencies can be stored.
Think of it this way; an analog audio signal is made up of an almost infinite sum of signals, that when combined make up the sound that you hear. To do this with a digital format, you must choose which of these signals to store because computers are finite machines. So the higher the bit rate, the more signals can be sampled and the better the quality of the sound.
